Non-rigid registration (NRR) of a group of images [6,4]
establishes correspondence among the set. That correspondence can
also be assessed using measures of overlap between labels in the images
[2] or by creating degraded test sets [5]
and attempting to recover a correct solution. A new method, which
has already been validated in 2-D, is proposed as the means for assessing
3-D registration of images of the brain. Ultimately, different NRR
algorithms can be compared and ranked based on their performance.
